The mother of the former U.S. Marine sentenced to death in Iran was allowed to visit her son, who she said looked gaunt and terrified on death row.

Amir Hekmati's mother, Benhaz, went to Tehran in late January, according to a report posted late Tuesday by The New York Times, three weeks after an Iranian court sentenced the 28-year-old Arizona-raised Iranian-American to death for "cooperating for a hostile country... and spying for the CIA."

"While he is disappointed by the circumstances he finds himself in, he is hopeful that the truth will be known and he will be able to come home very soon," Hekmati's mother said in a statement, according to The Times. She described the Iranian officials she met as "hospitable" and "respectful," but said her son looked thinner and shocked by his ordeal.

Hekmati's family has publicly maintained Hekmati's innocence, as first voiced by his father to ABC News in an exclusive interview before the death sentence came down.

"My son is no spy. He is innocent. He's a good fellow, a good citizen, a good man," Hekmati said in December. "These are all unfounded allegations and a bunch of lies."

Hekmati, an Arizona-born Iranian-American who served the U.S. Marines as a rifleman from 2001 to 2005, was arrested while visiting his extended family, including two elderly grandmothers, in Tehran on Aug. 29, 2011, according to the family. The family said they were urged by the Iranian government to keep quiet about his arrest with the promise of later release, but then in December, Hekmati was shown on Iranian television allegedly confessing to being an undercover agent of the Central Intelligence Agency on a mission to infiltrate the Iranian Intelligence Ministry.

"It was their [the CIA's] plan to first burn some useful information, give it to them [the Iranians] and let Iran's Intelligence Ministry think that this is good material," Hekmati says calmly in the video.

Contrary to claims made during the initial Iranian broadcast, Hekmati's military record, provided to ABC News, shows that he never had intelligence training and the U.S. State Department said in early January Iran's claims that Hekmati "either worked for, or was sent to Iran by the CIA are simply untrue."

"The Iranian regime has a history of falsely accusing people of being spies, of eliciting forced confessions, and of holding innocent Americans for political reasons," State Department spokesperson Victoria Nuland said then.

With the exception of the rare family statement criticizing Iran's previous lack of cooperation, Hekmati's kin, now represented by a high-powered attorney and a public relations firm, have been quiet in their dogged efforts to free the 28-year-old.

"By remaining discreet, you are not ruling out the option to be more public later," the family's lawyer in America, Pierre-Richard Prosper, told The Times. "A more visible campaign has not been ruled out."

Shortly before Benhaz's visit, Hekmati's lawyers in Tehran filed an appeal with courts in Tehran.

Eric Volz, a spokesperson for the family, did not immediately respond to ABC News' request for comment on this report, but Volz confirmed Hekmati's mother's visit to The Associated Press. A website set up by representatives of the family, FreeAmir.org, posted The New York Times' story in place of a new family statement.

This man couldn't be a spy. He is for all purposes nothing useful to intelligence gathering. They forced a confession out of him (as Iran has a history of doing, including to their own citizens) and now they are going to kill him for the sole purpose of inflaming America.

I'd believe it's important in intelligence gathering to hire as many as possible ideologically or financially interested agents in the target country, spies can be completely normal people who are there to provide intelligence about public opinion or activities of a nearby important installation for example.

Sometimes it's also just impossible to find out effective agents and you have to resort for the best you can get just to have some picture of happenings inside a nation.

Edit: And contrary to popular belief, spies are usually people who already live in the target country or are about to travel there on business for example, preferably natives of the target nation.

Is it somehow hard to believe that Iran is of interest to US and therefore US spies on Iran? And sometimes the spies even get caught!?

Edit: So yeah I guess it's a succesfull tactic to make losing a spy into a propaganda victory.

For some odd reason, my mind completely messed up the head line to think that the mother was being sentenced to death for visiting her ex-U.S. Marine.
Then I figured that it was a retarded thought and read the article to see what is going.

Actually, yes. Marines (Infantry specifically) are the most selected for jobs as agents in the FBI and CIA.

I suppose all you peter puffers that are disagreeing have first had experience like I do, right? I'm not lying. You fulfill almost all of of the pre-reqs that they look for just by being an Marine Corps infantry. Specifically infantry because you go through more physical training, combat training and have a higher security clearance than other jobs in the Marines.
